This is a little command-line utility which will help you quickly classify images into categories.
It won't do any fancy sub-image segmentation or anything. Each image has one tag.
For example, let's say you have a directory animals/ full of pictures of cats and fishes, and you want to tag each picture as either a "cat" picture or a "fish" picture. You can create a directory with subfolders cat/ and fish/, and run the program like so:
$ ls dataset/
cat fish
$ cargo nightly build --release
$ ./target/debug/tagimg -i animals -o dataset
this will create a webserver on port 8000. Visit http://localhost:8000/ and start clicking buttons - as you do, images will be moved from animals/ into the appropriate folder under dataset/.
